getTimestamp

public long getTimestamp()

getDims

public Object[] getDims()

getRowIndex

public int getRowIndex()

estimateBytesInMemory

public long estimateBytesInMemory()

bytesInMemory estimates the size of IncrementalIndexRow key, it takes into account the timestamp(long), dims(Object Array) and dimensionDescsList(List). Each of these are calculated as follows:

• timestamp : Long.BYTES
• dims array : Integer.BYTES * array length + Long.BYTES (dims object) + dimsKeySize(passed via constructor)
• dimensionDescList : Long.BYTES (shared pointer)
• dimsKeySize : this value is passed in based on the key type (int, long, double, String etc.)

Returns:

long estimated bytesInMemory
